Rice Husk Ash Market Size, Share & Industry Analysis, By Silica Content ( 80-84%, 85-89%, 90-94%, Above 95% ), By Application ( Construction & Infrastructure, Steel Industry, Ceramic & Refractories, Silica Production, Others ) and regional Forecast, 2024-2032

Rice husk ash is a valuable green resource procured by burning the protective outer covering of rice husk, having great potential, the husk of the rice is removed in the farming process before it is consumed. It also has high pozzolanic reactivity and contains a high specific surface area of non-crystalline silicon dioxide (SiO₂), thus making its chemical complexion very similar to that of micro silica, as the rice husk itself has a very rough surface, it is abrasive in nature. These are hence resistant to natural degradation hence resulting in improper disposal problems.

The chemical characteristics inherited by rice husk ash are silicon dioxide (SiO₂), aluminium oxide (Al₂O₃), ferric oxide (Fe₂O₃), magnesium oxide (MgO), calcium oxide (CaO), sulphur trioxide (SO₃) and carbon (C). However, the final composition of the useful rice husk ash may vary depending upon the source as well as the type of treatment. The method of heating can also bring changes in the overall chemical constituents of the ash. The silicates are one of the primary components of the final product. During the burning process, the components that are volatile in nature are evaporated, and the only component left is the silicates. The rice husk ash to be more precise have characteristics based on the components, the temperature of burning, and the time of burning.

The rice husk ash market is segregated into silica content, application, and geography. Based on silica content, the market is segmented as 80-84%, 85-89%, 90-94%, and above 95%. Based on application, the global industry can be majorly divided into construction & infrastructure, steel industry, ceramic & refractories, silica production, and others. Blending of rice husk ash in cement has become a common recommendation almost in the entire construction sector as it has pozzolanic reactivity, thus increasing the durability and strength of cement. As rice husk ash contains huge amounts of silica, the extraction of this silica for economic purposes is observed. Rice husk ash is also utilized in the production of high-quality flat steel, insulation purposes, and more.

The easy availability of rice husks to produce the required residue at relatively low prices is set to propel the global rice husk ash market. Rice husk ash can improve and provide good compressive strength to the concrete and split tensile strength. The product also contains a high amount of silica content, enabling it to be a suitable supplementary cementitious material. .When compared with ordinary portland cement (OPC) concrete, the addition of rice husk ash significantly improves the corrosion resistance and strength, leading to the formation of strong bonds. Additionally, it also possesses a good shrinkage property and enhances the durability of concrete and decreases leachability.

Rice husk has a very low nutritional value, and as they take very long to decompose are not appropriate for composting or manure. The several million tonnes of rice husk ash produced globally can have negative impacts on the environment if not disposed of properly. Suitable incinerators and grinding methods are used to burn and grind rice husk to get a better quality of ash for construction purposes. The process of burning and grinding needs to be carried out correctly to get the ash in a form.

Key Players Covered:

Some of the major companies operating in the rice husk ash industry are Guru Metachem Pvt. Ltd, Usher Eco Power Ltd, Yihai Kerry Investments Co., Ltd, RESCON, Jasoriya Rice Mill, Deelert, Wadham Energy Limited Partnership, Agrilectric, Agrisil Holding, and Refratechnik Italia S.r.L.

Regional Analysis:

The rice husk ash market can be mainly segmented into five geographical locations, including North America, Asia Pacific, Europe, Latin America, and Middle East & Africa. Asia Pacific is expected to exhibit maximum potential for the players of the global rice husk ash market. The development of the region is the result of the exponential development of various nations such as India. Furthermore, the easy availability of raw materials in numerous countries owing to rich agricultural heritage is also set to propel the industry outlook. The Middle East & Africa industry size is also projected to grow at a significant pace owing to its perpetual economic development coupled with heavy investments in the infrastructure sector. The construction industry in the region is also anticipated to undergo substantial investments over the coming years due to the new development projects accelerating the demand for rice husk ash in the region.
